An electronic apparatus is provided. The electronic apparatus includes a signal receiver configured to receive a first wireless signal; a signal transmitter configured to output a second wireless signal; and a processor configured to: identify an external apparatus based on an input key indicated by the first wireless signal as the first wireless signal is repeatedly received through the signal receiver; identify the second wireless signal based on the input key and the external apparatus; and control the signal transmitter to repeatedly output the second wireless signal while the first wireless signal is repeatedly received. Each of the first wireless signal and the second wireless signal alternately comprises a signal section corresponding to the input key and an idle section, and the processor is further configured to control the signal transmitter to output the second wireless signal during the idle section of the first wireless signal.

2. The electronic apparatus according to claim 1 , wherein each of the plurality of second signal sections of the first wireless signal is identified as noise by the external apparatus.
3. The electronic apparatus according to claim 1 , wherein the first wireless signal further comprises a fourth signal section, and wherein each of the plurality of second signal sections is shorter than the first and fourth signal sections.
4. The electronic apparatus according to claim 3 , wherein the first and fourth signal sections comprise the input key data, and wherein each of the plurality of second signal sections does not comprise the input key data.
5. The electronic apparatus according to claim 4 , wherein each of the plurality of second signal sections is identified as noise by the external apparatus.
6. The electronic apparatus according to claim 1 , wherein the second wireless signal comprises a fifth signal section shorter than the third signal section.
7. The electronic apparatus according to claim 6 , wherein the third signal section of the second wireless signal comprises the input key data identifying the input key, and wherein the fifth signal section of the second wireless signal comprises no input key data and is identified by the external apparatus as equivalent to the third signal section of the second wireless signal.
8. The electronic apparatus according to claim 1 , wherein the processor is further configured to operate based on the input key indicated by the first wireless signal in a first mode, and control the second wireless signal, which is targeted to be recognized by the external apparatus, to be output based on the first wireless signal in a second mode.
9. The electronic apparatus according to claim 8 , wherein the processor is further configured to control the second wireless signal, which has a longer period than the first wireless signal, to be output based on the first wireless signal in the second mode.
10. The electronic apparatus according to claim 1 , wherein the first wireless signal further comprises a sixth signal section, wherein the sixth signal section of the first wireless signal is shorter than the first signal section, and wherein the processor is further configured to control the second wireless signal to be output based on the sixth signal section.
11. The electronic apparatus according to claim 1 , wherein the first wireless signal comprises first to nth signal sections, and wherein the second wireless signal comprises a blank section subsequent to the first signal section.
12. The electronic apparatus according to claim 1 , wherein the first wireless signal comprises signal sections which are different in length and alternately provided.
13. The electronic apparatus according to claim 12 , wherein the processor is further configured to control the second wireless signal to be output based on a short signal section of the first wireless signal.
14. The electronic apparatus according to claim 13 , wherein the short signal section comprises no input key data.
15. A method of controlling an electronic apparatus, comprising: receiving a first signal section and a plurality of second signal sections of a first wireless signal, the plurality of second signal sections being repetitively received after the first signal selection, and each of the plurality of second signal sections being shorter than the first signal section; based on the first signal section corresponding to an input key, identifying an external apparatus to operate according to the input key; and based on the plurality of second signal sections of the first wireless signal being repetitively received, repetitively outputting a second wireless signal, so that the identified external apparatus receives the second wireless signal and operates according to the input key, wherein the first wireless signal comprises the plurality of second signal sections and a plurality of idle sections which alternate with each other based on a given period, wherein a third signal section of the second wireless signal is output in an idle section of the first wireless signal, wherein the first signal section comprises input key data indicating the input key, and wherein the plurality of second signal sections do not comprise the input key data.
16. A display apparatus comprising: a display configured to display an image; a signal receiver configured to receive a first wireless signal, the first wireless signal comprising a first signal section and a plurality of second signal sections that are repetitively received after the first signal section, each of the plurality of second signal sections being shorter than the first signal section; a signal transmitter configured to output a second wireless signal; and a processor configured to: based on the first signal section of the first wireless signal received through the signal receiver corresponding to an input key, identify an external apparatus to operate according to the input key; and based on the plurality of second signal sections of the first wireless signal being repetitively received through the signal receiver, control the signal transmitter to repetitively output the second wireless signal, so that the identified external apparatus receives the second wireless signal and operates according to the input key, wherein the first wireless signal comprises the plurality of second signal sections and a plurality of idle sections which alternate with each other based on a given period, wherein the processor controls the signal transmitter to output a third signal section of the second wireless signal in an idle section of the first wireless signal, wherein the first signal section comprises input key data indicating the input key, and wherein the plurality of second signal sections do not comprise the input key data.
